Steps from Piazza del Campo, a renovated 17th-century apartment in Energy Class A4, air-conditioned and fully furnished, for sale in Siena. In the vibrant heart of Siena, just steps from Piazza del Campo, this rare studio apartment is set within a prestigious 17th-century palazzo of extraordinary architectural character. The property, 33 sq m/355 sq ft on the first floor, harmoniously combines historic charm with modern comfort. A grand wooden front door opens onto a magnificent entrance hall where the grandeur of the 1600s is immediately felt: soaring ceilings, original stonework, and a sweeping stone staircase lead to a large, serene internal courtyard. It is onto this beautifully preserved courtyard that the apartment's windows face, ensuring exceptional quiet and privacy, a rare privilege at the very centre of one of Italy's most celebrated cities. The layout, thoughtfully designed following a functional 2012 renovation, features an entrance hall leading to a bright windowed bathroom with shower cubicle, before a short internal staircase ascends to the airy open-plan living area above, with recessed spotlights, laminate flooring, a fitted kitchenette, and a double sleeping area. Fully furnished and equipped with double-glazed wooden frames, mosquito screens, fibre optic broadband, and a heat pump air conditioning system, the apartment achieves the prestigious Energy Class A4 rating, a remarkable result for a building of this age. Currently operated as a holiday let, it represents the perfect Sienese pied-à-terre and a prestigious income-generating investment.
